Another Sod Question.

I have a bid for a job that is 5 houses that need sod. Three of them are next door to one another and the other two are next to each other right across the street. I estimate there will be 3600 yds of sod for all 5 houses. The lots are mostly flat. My question is how long would it take 3-4 guys to lay this? I would like some guesses using small and big rolls. Thanks
